我如何获得黄瓜和腌菜使用mongo_mapper，machinist和machinist_mongo？ [英] How do I get cucumber and pickle working with mongo_mapper, machinist, and machinist_mongo?

问题描述

我想获得机械师， machinist_mongo ， mongo_mapper ，黄瓜和 pickle 一起玩。

I would like to get machinist, machinist_mongo, mongo_mapper, cucumber and pickle to play nice together.

目前我有机械师与我的所有蓝图配置和我使用黄瓜做BDD。到现在为止还挺好。我的问题是我必须为我的所有机械师蓝图写自定义黄瓜步骤。这不是一个真正的问题本身，因为它不是阻止我在我的轨道，但作为一个.NET开发人员检查rails，感觉非常脏，必须为每个蓝图写一个步骤，而在.NET我可能使用反射。

Currently I have machinist with all my blueprints configured and am using cucumber to do BDD. So far so good. My problem is I am having to write custom cucumber steps for all of my machinist blueprints. It is not really a problem per se, since it is not stopping me in my tracks, but as a .NET dev checking out rails, it feels really dirty to have to write a step for each blueprint whereas in .NET I could probably use reflection.

有什么办法我可以得到pickle的内置 capture_model ， capture_plural_factory 等，以识别我的机械师蓝图？

Is there any way I can get pickle's built in capture_model, capture_plural_factory, etc, to recognize my machinist blueprints?

我很自信我的机械师配置和设置正确，因为当我使用 blueprintname.make ，在自定义黄瓜步骤中，一切正常。

I am pretty confident I have machinist configured and set up correctly, because when I use blueprintname.make, in a custom cucumber step, everything works out correctly.

code> config.adapters = [：machinist，Machinist :: MongoMapperAdapter] 但我得到一个错误，说明没有方法工厂 Machinist :: MongoMapperAdapter 。

I tried using config.adapters = [:machinist, Machinist::MongoMapperAdapter] but I get an error stating that there is no method factories for Machinist::MongoMapperAdapter.

未定义的方法`factories' MongoMapperAdapter：Class（NoMethodError）/usr/local/lib/ruby/gems/1.8/gems/pickle-0.3.0/lib/pickle/config.rb:25:in`factories'

undefined method `factories' for Machinist::MongoMapperAdapter:Class (NoMethodError) /usr/local/lib/ruby/gems/1.8/gems/pickle-0.3.0/lib/pickle/config.rb:25:in `factories'

features / support / machinist.rb：

require 'machinist'

Before { Sham.reset } # reset Shams in between scenarios

spec / blueprints.rb（为了清楚起见，截断）

spec/blueprints.rb (truncated for clarity)

require 'sham'

Sham.code { Faker::Lorem.words 1 }

AccessCode.blueprint do

class AccessCode
  include MongoMapper::Document

  key :code, String, :required => true
end

推荐答案

头对墙，我有一切都工作（我说大多是工作，因为我不知道如果有什么问题，我还没有发现）。

After days of beating my head against the wall, I have everything mostly working (I say mostly working because I'm not sure if there is something wrong that I haven't discovered yet). The fix was actually pretty simple once I figured it out.

要解决这个问题，并获得我的黄瓜步骤使用泡菜，我更改了 MongoMapper :: Document 包含 Pickle :: Adapter :: Base 。我使用了来自的lib / pickle / adapters / active_record.rb和data_mapper.rb（与active_record.rb相同的路径）泡菜为例。我仍然需要 machinist_mongo ，大概是把我的机械师蓝图挂钩。

To resolve the issue, and get my cucumber steps working with pickle, I changed MongoMapper::Document to include Pickle::Adapter::Base. I used lib/pickle/adapters/active_record.rb and data_mapper.rb (same path as active_record.rb) that come with pickle as an example. I did still need machinist_mongo, presumably to hook up pickle to my machinist blueprints.

我不能把 def self.model_classes 中的代码归功于它从 tjtuom's pickle fork 。

I can't take credit for the code in def self.model_classes - it is stolen from tjtuom's pickle fork.

PS。如果这是完全错误的做法，请随意批评或提出建议，我是一个完整的ruby noob。

PS. If this is the completely wrong way to do it, please feel free to criticize or give suggestions, I am a complete ruby noob.

module MongoMapper::Document
  module PickleAdapter
    include Pickle::Adapter::Base

    def self.model_classes
      @@model_classes ||= ::MongoMapper::Document.descendants.to_a +
        ::MongoMapper::Document.descendants.map { |klass| klass.subclasses }.flatten
    end

    # get a list of column names for a given class
    def self.column_names(klass)
      klass.column_names
    end

    # Get an instance by id of the model
    def self.get_model(klass, id)
      klass.find(id)
    end

    # Find the first instance matching conditions
    def self.find_first_model(klass, conditions)
      klass.find(:first, :conditions => conditions)
    end

    # Find all models matching conditions
    def self.find_all_models(klass, conditions)
      klass.find(:all, :conditions => conditions)
    end
  end
end

为机械师设置酸洗：

Pickle.configure do |config|
  config.adapters = [:machinist]
end

要配置 mongo：

To configure database_cleaner for mongo:

require 'database_cleaner'
require 'database_cleaner/cucumber'

DatabaseCleaner.orm = 'mongo_mapper'
DatabaseCleaner.strategy = :truncation
